摘　　要：为分析无核密度仪检测沥青路面压实度的稳定性与适用性,利用特克斯勒无核密度仪,对沈山高速公路路面维修工程沥青路面压实度进行检测,并对相关检测数据进行了分析,分析结果表明,无核密度仪测量数据稳定,经过与芯样的实测密度修正后,其测量值与实际值偏差在3kg/m 3以内,无核密度仪检测可作为路面压实度离析程度评价以及路面不适于取芯时压实度的评价。In order to analyze the stability and applicability of non-nuclear densitometer in detecting the compactness of asphalt pavement,Troxler non-nuclear densitometer is used to detect the compactness of asphalt pavement in Shenshan Expressway pavement maintenance project,and the relevant test date are analyzed.The analysis results show that,the measured data of non-nuclear densitometer is stable,and the deviation between the measured value and the actual value is within 3kg/m 3 after the correction with the measured density of the core sample.The detection of the non-nuclear densitometer can be used as the evaluation on the segregation degree of pavement compactness and the evaluation on the pavement compactness not suitable for coring.
